Clarence Larkin's Diagram of the Great Pyramid of Giza
Isaiah 19:19-20 says, "In that day shall there be an altar to the LORD in the midst of the land of Egypt, and a pillar at the border thereof to the LORD. And it shall be for a sign and for a witness unto the LORD of hosts in the land of Egypt: for they shall cry unto the LORD because of the oppressors, and he shall send them a saviour, and a great one, and he shall deliver them."
There is a place in the "center of Egypt" that sits on the border between Upper and Lower Egypt. I would suggest that either in the days of Isaiah, or when Christ shall return, that it is the location of the Great Pyramid. The structure is presently missing the capstone, or the "chief cornerstone" (Eph. 2:20). The "King's Chamber" has for it's base, the fiftieth layer of stone, and as the highest place, it represents Heaven. The "tomb's" sarcophagus is empty (Mt. 28:6)!
There is a chamber beneath the "King's Chamber" which has fittingly been named the "Bride's or Queen's Chamber." One enters it by walking in a horizontal, narrow passageway, representing following Christ on earth (Mt. 7:14).
There is one final chamber which is literally beneath the pyramid, under ground. I has finished walls and ceiling, but the bottom is jagged stone. It is known as the "bottomless pit" (Rev. 20:3). When one enters the pyramid, the passage, which is aliened with the star "Alpha Draconis," (the Star of the Dragon), is descending toward the "bottomless pit." There is a single, narrow passage leading upward toward the "King's Chamber," off of which is the entrance of the passage to the "Bride's Chamber." The ascending passage, from that point on, becomes the "Grand Gallery," which is a huge passageway.
An empty tomb, awaiting it's Chief Cornerstone, is a witness to Jesus Christ in Egypt.
